Japan Line Ltd. & Mitsui O.S.K. Lines Ltd., documented joint operation

Mitchell places J100 and J101 on a joint Japan Line and Mitsui O.S.K. card for Godwit and also refers to Jasmin Shipping. Japan Stork and Japan Margaret are named, the latter possibly meaning Japan Marguerite. The Godwit line drawing instead shows a red funnel, leaving the variant relationships unclear.
